Application led September 10, 1909. Serial No. 517,133.

To all whom it may concer/n:

Be it known that l, Josemi J. Cosonovn, a citizen of the vUnited States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inf vented certain new and useful Improvements in YWater-Closet Connect-ions, of which the following is a specification.

This invention has relation to water closet connections and has for its object the provision of novel means for connecting a water-closet, or similar article which rests on the licor, to a soil pipe, in such manner as to, avoid the breaking of the soil pipe or of the lioor flange ot' the closet or the floor flange of the connection or any other damage to the closet, the connection, the soil .pipe or any of the several joints thereof, by the settlement of the soil pipes.

il further object of the invention is to pre-` vent the water-closet being raised from the iioor and held in that position by the settlenient or shrinking of the walls or floors of the building and a still ,further object of the invention is to providecineans for vertically adjusting,r the seat formed in the soil pipe connection for the reception of the end of the outlet passage of the closet.

l t has been found that in many cases, particularly where water-closets are installed in new buildings, the 'building or the soil pipe or both, are liable to settle and either break or disarrange sonic of the parts and permit leakage ot' water or gas and this invention consists in the provision of a novpl forinoii oxpansiblc and flexible connection between the water-closet and the soil pipe which will permit of relative movement of these parts without detriment. to either or impairment of any of the joints therebetween.

ln carrying iny invention into etect l pro vide an eXpansible and flexible connection pipe or conduit composed ot' flexible metal such as lead, copper or the like. circumferentially corrugated or ribbed and grooved or undulated so as to permit of its being expanded or contracted lengthwise without fracture. attacl'icd at one end to the soil pipe and at the other end to a flanged bell or socket that receives the projecting portion of the outlet' passage lor" the closet and permits ol any possible relai ive movement of the closet. and soil pipe due to shrinkage or settlement or any other movement of the building or soil This connection pipe or conduit is pipe without detriment orl damage to any of the parts, joints or connections.

Referring to the accompanying drawings:

Figure l 'is a vertical sectional view of a A portion of a water-closet and a portion of a vertically arranged soil pipe with my improved connection applied thereto. Fig. 2 is a similar view showing my connection in modiiied form applied to a horizontally arranged vsoil pipe.

The bowl or closet is designated 1 and is of the usual `or any desired type and is formed with the outletA passage 2, 'terminating in a projection 3, which may be, as shown, a metallic thinible screwing into the mouth of Athe outlet passage. The loor flange of the closet is designated il and is.

hollowed out at 5, to receive the floor iiange G of a socket or bell 7, the lower surfaces of the flanges 4 and 6 being on a horizontal line and both bearing on the licor and the socket or bell receiving the thinible 3 and making a tight metal to metal joint therewith.

In `ltig. l which shows my improved connection in the form known as a bend, the connection is designated 8 and consists of a section of curved' metal pipe which is ren dered flexible for a portion of its length by being corrugated, undulated, or ribbedy and grooved as at 9, thecorrugations, undulations-or ribs and grooves being parallel and of any desired or required contour, preferably that illustrated and in which theribs4 and grooves are devoid ot sharp angles and the walls of the internal grooves are at suiicient angle to the longitudinal axis of the pipe to prevent the lodgment of solid inatter thereupon.

' The bend 8, is connected to the socket or bell 7 by an ordinary. soldered jointl 10 and is connected to a vertically arranged soil pipe (not shown) by a T-Y 1l, a nipple 12 being interposed between the bend 8 and the T--Y ll and attached to the bend by a wiped joint 1S and secured in position in 'the T-Y by calking 14.

ln Fig. 2 of the drawing the connection is designated l5 and is straight.instead of b eing curved as in Fig l and is rendered fleetible for a portion of its length by being corrugated, undulated or ribbed and grooved at 1G, in the same manner as the bend 8.

The connection 15 is socket or bell 7 by a soldered joint l0, and is connected to a horizontally arranged, soil attached to the nlpple 18, being interposed between the conf nection and the T-Y 17 and attached to the connection 15 by a soldered joint 19 and to the. T Y 17 by a screw-threaded end 2O that screws into the threaded faucet of the T-Y, a nut 2l being formed on the nipple to facilitate screwing it into the T-Y.

In practice, the bell or socket, the connection and the.T-Y being attachedl together and placed in position in the floor and walls, the bowl or closet is placed in position on the floor, the floor fiange l of the bowl or closet 1, covering the floor fiange G bf the bell or socket 7. The floor fiange of the bowl or closet is connected to the floor fiange of the bell or socket by means of suitable bolts shown in dotted lines and designated 2Q. The tightening up of these bolts brings the thimble 3 tightly to its seat in the bell or socket, thus making a tight metal to-metal joint between the thimble and its seat in the bell or socket.

As it is difficult in manufacturing closets to so exactly locate or fit the thimble that it will exactly seat while the floor flanges of both the closet and thev bell are in contact `with the floor, the flexible lconnection will,

if the thimble does not contact 'with its seat, be drawn out or'expanded longitudinally in tightening up the bolts, so as to permit a tight joint-to be made between the thimbl'e and its seat in the bell or socket. On the other hand if the tliimble seats before the closet rests on the floor, the latter may be recessed and -the bell pressed down, the connection being compressed and shortened by this operation.

' -After the parts have been connected up as described, various changes may take place in the relative positions of the closet and 4the soil pipe by the settlement or shrinkage 'of the buildingI or of some parts of the drainage system. The floor may sink in a vertical direction relatively to the soil pipe, thus lowering the closet, or the soil pipe may sink or settle in a vertical direction while the floor remains stationary, orbotli the` floor and the soil pipe may sink vertically but to different degrees, or one may change its angle relatively to the other. These and many other contingencies that may arise will be all automatically compensated for without detriment to any of the parts or any impairment of the integrity of the joints by the flexibility of the corrugated connection, which will yield lengthwise in either' direc tion, being lengthened or shortened accordingly as it is subjected to tension or to ,compression. Even a change in the relative an4 gular position of' the closet and the soll pipe' will not deleteriously affect the system as, in such an event, the flexible connection will be expanded on one side and contracted on. the

one piece, soft metal pipe or conduit, located below the floor line of the closet and connected by means of a floor flange and soldered joint to the closet bowl and by means of a soldered joint and a nipple to the soil pipe.

2. The combination with a water-closet and a soil pipe of a longitudinally and laterally flexible pipe or conduit connected to the water-closet and to the soil pipe.

8. The combination with a water-closet and a soil lpipe of a longitudinally and laterally iiexible soft metal. pipe or conduit connected to the water-closet and to the soil pipe.

4. The combination with a water-closet and a soil pipe of a longitudinally and laterally flexible pipe or conduit having circumferential corrugations, saidpipe being connected to the water-closet and to the soil pipe.

5. The combination with a' water-closet i and a soil pipe of a longitudinally and laterally fiexiblc soft metal pipe or conduit having circumferential corrugations, said pipe being connected to the water-closet and to the soil pipe.

G. The cmbinationwvith a water-closet and a soil pipe of a longitudinally and laterally flexible soft metal pipe having corrugations completely surrounding the pipe for a portion only of its lengthand being connected to the water closet and the soil pipe. 7. The combination with a water-closet and a soil pipeof a soft metal bend conA nected tothe water-closet and to the soil pipe, said bend having a portion of its length laterally and longitudinally fiexible and the remainder of its length rigid.

In testimony whereof l have affixed my signature, in presence of two witnesses.
